Confinement of Electrons to Quantum Corrals on a Metal Surface

A method for confining electrons to artificial structures at the nanometer lengthscale is presented. Surface state electrons on a copper (111) surface were confined to closed structures (corrals) defined by barriers built from iron adatoms. The barriers were assembled by individually positioning iro...
